Abstract

Sekolah Menengah Atas (SMA), Sekolah Menengah Kejuruan (SMK) atau yang sederajat menyelenggarakan ujian kenaikan kelas menggunakan Computer Based Test (CBT). Akan tetapi, dalam pelaksanaanya mengalami permasalahan, salah satunya beban server. Hal tersebut diakibatkan oleh permintaan pengguna yang melebihi kemampuan server. Untuk mengatasi permasalah tersebut digunakanya load balancing web server menggunakan haproxy. Namun penggunaan load balancing web server, sering mengalami inkonsistensi data tiap server. Oleh karena itu digunakan replikasi database yang dapat menjamin konsistensi data dalam load balancing web server. Penelitian ini menggunakan pendekatan deksriptif dengan metode perancangan sitem jaringan PPDIOO. Ada dua algoritma load balancing yang dibandingkan, yaitu algoritma round robin dan algoritma least connection. Berdasarkan hasil pengujian httperf, parameter throughput kedua algoritma memperoleh nilai rata-rata yang sama yaitu 99,5 Kb / second. Pada pengujian parameter response time algoritma least connection lebih unggul yaitu 6,9 ms dibandingkan dengan round robin yang memiliki nilai rata-rata sebesar 7,2 ms, namun pada pengujian parameter CPU Utilization algoritma round robin bernilai 23,7 % lebih unggul dibandingkan algoritma least connection yaitu 24,3 %.

Abstract

Currently informarsi system is needed by several large companies. To support some data processing, one of them is employee data processing and employee contract data. Given the existing problems in contract data pengelohan often occurs that the check is not maximal so some data left behind and even neglected impact on the increase in salaries of employees who are late due to contracts that are not handled according to schedule. This study aims to create a web-based RIL application using sms gateway for delivery of contract data reminder information. This research uses SDLC method with Extreme Programming model with stages of planning, designing, coding, testing, implementation and evaluation. SMS gateway is a gateway for information dissemination using SMS. With SMS gateway can spread the message of the serial number automatically and quickly which is directly connected with the database of mobile numbers that have been stored. This can be done by RIL applications in sending reminder information messages to the HRD division as well as employees receiving their contract expiration date information. The result of the research is the user can maximize the checking of contract data so that nothing is left behind and give the report that arranged well and clear

Abstract

The research was conducted in the field of steganography. Discrete Cosine Transform (DCT) is a method used in the insertion technique. The results of steganography have problems if they look blurry, have low levels of similarity and high error values. One way to solve this problem is by proposing image interpolation. The interpolation method consists of various kinds and gives each other advantages. This study intends to compare three kinds of interpolation techniques to find the best one. The three interpolation techniques are bilinear, nearest neighbor, and spline. The method used in this research is experimental. Images with extension formats * .tif, * .png, and * .bmp with dimensions of 512x512 px are interpolated by scaling 1.5, 2, and 4. The results of the interpolation process are used to insert messages in * .txt format of 157 bytes with discrete cosines transform (DCT). The image quality of the message insertion is measured by the MSE and PSNR values. The result of the message insertion test shows that the value of the image quality is directly proportional, meaning that if the condition of the message size is fixed and the cover dimensions are greater, the MSE value will be smaller and the PSNR value will be greater. Images with * .tif and * .bmp extension formats have good stability, * .png images vary in size. The smallest error value test results were obtained in the spline interpolation technique and this method when compared to the other two techniques had the lowest average MSE value of 8.221 and the PSNR value of 40,301 dB.
